ABSTRACT:
An improved printed circuit board layout is provided in which a transistor or a resistor (preferably a zero ohm resistor) can be installed. If a transistor is installed, this allows for selectively passing a signal; if a resistor is installed, the line is directly coupled. The resistor and transistor are surface mount devices, and the two pads for the resistor are overlapped with two of the pads for the source and the drain of the transistor. A separate pad is provided for the gate of the transistor. In this way, alternatively either a resistor or a transistor can be installed, but the trace links, stubs, and resulting undesirable effects are minimized through the overlapping pads.
